Hi our server was rebooted yesterday and when it came back online i saw the sqlserver wasn't connecting when i tried to restart the process its starts briefly then stops after a few seconds in the logs tail i see these statements. When i try to go into sql studio to try and look at the properties setting or to try and backup and truncate i cant because it will not connect to the instance since msqlserver service keeps stopping. Ive tried to put in single user mode the T flags i still cant get it to work and keep the process up so i can see whats going on. Can someone explain if they ever seen this
